kdmx2 is a program designed to split GDB packets and other trafic coming
from a target on a serial line into 2 separate pseudo-ttys.

The most common use of this is to run kgdb and console on a single serial
port, but should be usable for alternating gdbserver or console over a serial
line as well.

kdmx2 provides a few options :
	-d	Enable debugging.  This will dump all I/O from the
		serial port and 2 pseudo-ttys to standard error.  this
		output is well formatted and could be further reformatted
		if something more is desired (such as an something emulating
		'tail -f' of any of the three).
	-p	Path to the serial port to use.  An OS-dependant default
		for the first serial port is assumed, but any serial port
		can be used.
	-b	Baud rate.  kdmx2 will always initalize the serial port before
		use.  We default to 9600 8n1.  We do not allow for
		initalization to anything other than 8n1.  We allow for any
		valid baud rate between 9600 to 230400 to be used.  This
		however cannot be changed while the program is running.

To exit from kdmx2, kill the program or issue a control-c.
